Water Baptism represents two spiritual things that have already happened.
1. I have died.
Or aren’t you aware that all of us who were baptized into Christ Jesus were baptized into His death?
2. I have a new life.
We too may walk in newness of life. For if we have been united with Him like this in His death, we will certainly also be united with Him in His resurrection.
My death and new life are practiced by faith in Christ and his promises.
So, you too must count yourselves dead to sin, but alive to God in Christ Jesus.
